Title: Photographic copying on to lenticular films
Filed: 1955-03-29
Abstract: 806,872. Photographic printing on to lenticular films. CIBA Ltd. March 29, 1955 [March 29, 1954], No. 9190/55. Class 98(2) Colour separation images formed of material having substantially no scattering effect on light are contact-printed on to lenticular films, thus avoiding the complexity of optical printing and also the defects by scattering when silver images are so contact-printed. The non-scatter images may be of colloidally dispersed metal as of Specification 701,529, but are preferably of dyestuffs resulting from the primary colour development process as defined by Friedman, using little or no sulphite in the developers; and the yellow or brown images so made may be increased in gradation by dyeing with basic dyestuffs for which they have an affinity, followed by a tanning treatment to avoid bleeding of the dyes. Various controls for the exposure and processing of the lenticular films are described, including (1) minimizing scatter by avoiding deep penetration of the exposing light (2) producing a weak reversed image by uniform exposure from the rear, (3) partial bleaching as by Farmer's reducer, (4) blackening by hydrosulphite instead of re-exposure in reversal processing with, if desired, partial fixation or removal of some of the gelatin by a pepsin or pancreatin bath before such blackening, and these controls are featured in examples in which, Example 1, separation negatives obtained by means of a beam splitting camera are contact-copied on to silver bromide film, and these are brushdeveloped in alkaline 1-anilido-2-oxynaphtheline, bleached, fixed, dyed in Rhodamine Ca in acid solution containing ethylene oxide and p-tertiary octyl-phenol, and tanned in acidified tannin-formaldehyde solution. The non-scattering positives so made are contact-printed on film with transverse cylindrical lenticulations and an orthochromic emulsion containing a yellow-orange filter dye with green light using one-third of the illuminating surface for each, and such films are brush-developed in a specified metol-quinol developer, bleached in acidified permanganate, treated in sodium sulphite solution, blackened with hydrosulphite, fixed, washed and dried. Example 2 is directed to the production of non-scattering positives, these are developed with pyrogallol, acidstopped, bleached, fixed, dyed with Diamant Fuchsine and tanned in formaldehyde. Example 3 describes, somewhat as in Example 1, printing exposure of the lenticular film and then uniform rear exposure thereof with blue light, and such film is wound round a cylinder of artificial resin and rotated in a metol-quinol developer, bleached, treated in sodium sulphite and blackened as in Example 1, then lightly treated in Farmer's reducer, fixed and washed while still on the cylinder. The fourth and last Example describes pancreatin treatment for partial removal of gelatin from the lenticular film after exposure but before development. Exposure times and treatment solutions for all the examples are specified fully.
